This is undoubtedly the best freeware zip app out there. However, it does have some flaws which can make it frustrating to use. Firstly, it's slow. The UI is slow and the zip/unzipping is slow. Secondly, it's quirky. Things like, you can only drag items in/out of either side of the UI, but not via the top or bottom! Thirdly, it's not very stable. It does seems to crash a lot, especially when closing the UI. Overall though, it's the one I recommend because 1) it's free, 2) it works well mostly, and 3) it can handle almost any type of archive floating around. A definite thumbs up! ;-)
